SIGNALING MECHANISM.

Specification of Letters Patent.

Patented Apr. 3, 1917.

Application led November 8, 19,13. Serial No. 799,856.

To all whom t may concern.'

Be it known that I, HENRY E. Rnnvn, a citizen of the United States of America, and residing at New York, in the county of Kings and State of New York, have invented new and useful Improvements in Signaling Mechanism, of which'v the following is a specification.

My invention relates particularly to what are commonly termed electro-mechanical gongs. My Reissue Patent #12,914 of February 2nd, 1909, and my Patent #925,439 dated J une 15th, 1909, show constructions of the general4 character to which my present invention relates.

One object is to reduce the power required to rotate the hammer and to reduce the wear and tear caused by rotation of the hammer and to increase the speed of rotation of the hammer. Another object is to provide means for giving an alarm in case of breakage of the driving spring or in case the spring runsv down. Another object is to cheapen the construction of the winding shaft. Another object is to provide means for readily attaching the. casing to a conduit. Another object is to facilitate circuit terminal connection.l

vThe details of. construction by which the foregoing objects are carried out will be understood from inspection of the two accompanying sheets of drawings and `the following specification.

Figure 1, is a front View showing the striking mechanism and the conduit connection.

Fig. 2, is a side view of the same.

Fig. 3, is a view from the lower end showing the conduit connection 1n section.

Fig.'4, is a fragmentary detail view' showing apart of the conduit connection construction.

Figs. 5 and 6 are front and edge Views showing the electrical terminal connecting devices. L

Fig. 7, is an end view of the terminal. l

Fig. 8, is a front View of a modified form of terminal. l

Fig. 9, isgra front view similar to Fig. l

but showing a cover; and another form ofV conduit connection.

Fig. 10 is a side view thereof.

lfor instance, as rivets 47. The back Fig. 11 is a detail perspective view of the 2. The striking hammer 4 has an arm 5 carried by the shaft 6 and its pivot pin 7.

The conduit 30 (Figs. 1 and 2) carries the circuit wires for the control magnet and the alarm circuit. Along the rear vertical edge of the casing I provide an undercut chamber 31, the inner wall of which 32, carries the box terminals 33 and 34. Each terminal is suitably secured to the wall 32 for in stance, by means of one or more screws such as 35 properly insulated. In the form illustrated in the first three figures the chamber 31 is provided with upper and lower flanges or'walls such as 36 to-eachvof which the end of a conduit 30 is secured by means of an outlet nipple 37 and nut 38. The side of4 the chamber is closed by means of a cover 39. This cover has an outer flange 40 notched to receive attaching screws such as 41 and a rear flange 42 carryingone or more screws such as 43 which pass through notches inthe plate 44 at the back of the chamber and screw into the bar 45 at the rear. AEach wall strap 46 is secured to the back of the casing by suitable means sluch p ate 44 is secured between the straps 46 and the back of the casing.

Each of the circuit terminals 33 and 34 has a rigid main arm which with proper insulation is secured-to a wall of the main case. Each arm carries at its outer end a connecting plate 50 of novel construction. This plate is preferably of spring phosphorbronze of comparatively light gage. The plate 50 is secured to the main arm 33 by means of two screws 53, 53 tapped into the arm with clearance through plate 50. At'

the outer end of plate 50 a flange 51 is turned up. .The circuit wire 54 is clamped in the pocket formed by the screw head and flanged plate. The ange is notched at 51a and the plate is transversely bowed as indieffect upon the Wire even should the screws be accidentally loosened. In practice the wire is tightened under one screw head,then passed over the lug 52 to the second screw head where it is finally clamped, (see Fig.. 5). ln Fig. 8 a screw 55 is shown in place of the lug 52.

This device not only gives a maximum electrical contact surface, invaluable in equipments where a very small current is used, but also assures a strong locking effect preventing the wire from being torn from the terminal.

llt will be noted that the construction is such that the cover 39 may be readily attached or detached when desired. The circuit wires may be readily attached to or detached from the box terminals 33 and 34e and the conduit connections may be readily attached or detached to or from the box. or casing. rlhe undercut chamber keeps the parts compact and protected.

rlhe conduit connection illustrated in Figs. 9 to 13 is designed to facilitate the locate ing of the box in respect to a line of piping or conduit. ln this case the box is recessed or undercut at its rear edge, but instead of the end walls of the undercut terminal chamber being rigid with the box, they are carried by a separate part which is coupled into the conduit after which the box is applied thereto. This coupling member 85, is as shown in Fig. 1l, wholly separable from the box body and consists of the two spaced end walls 86, united by a back wall 87. ln practice, when putting up the conduit this member is simply interposed in the conduit at the point where the box is to be located. After the conduit is up and everything is in place, the box may then be applied to said coupling member and sccured in place by means of its wall straps, in the usual way. rlfhe open side of the coupling member is closed by a cover 88 which is illustrated as having a flange 89 on its rear edges hooking in under an upturned lip 90 on the member 85, the forward edge of the cover being clamped to the box by the nuts 91 on bolts 92. rl`his constructionI serves both to close up the terminal chamber and to tie the chamber to the box. ln Fig. 13 a rod 93 takes the place of the upturned lip for securing the flanged rear edge of the cover.

For the purpose of protecting the hammer from injury and against outside interference, there may be provided a cover 95, which incloses the hammer without interfering with its freedom of action.

Wiet l claim is l. lin/a device of the character described,

chamber and a cover for said chamber detachably secured to said casing.

3. Electromechanical gong apparatus, comprising a casing containing the mechanism and having an undercut chamber eX- tending along one vertical edge and means for looping and electrically connecting circuit wires in said chamber without cutting the wires.

4. Signal apparatus comprising, a casing having a chamber along a rear Vertical corner, wall-straps secured to the bottom of the casing, a back plate lfor said chamber secured between said straps and said casing and a cover for said chamber.

5. Signal apparatus comprising a casing having a chamber along a rear vertical corner, wall-straps secured to the bottom of the casing, a back plate for said chamber secured between said straps and said casing, a cover for said chamber and means for securing conduit sections in the upper and lower ends of said chamber.

6. In a devicev of the character described, a casing,a circuit terminal outside of said casing, spaced apart end walls and a back wall serving in conjunction with the outer wall of the casing to form an open sided chamber inclosing said circuit terminal, the said end walls being constructed for engagement by sections of conduit and a detachable cover closing the open sides of the circuit terminal chamber.

7. Llin electrical apparatus, a casing having projecting flanges at one side thereof forming in conjunction with the side of the casing a housing for an electric terminal open at one side, an electric terminal mounted in said housing,- said flanges being adapted for engagement with conduit sections and a detachable cover for said housing.

8. ln electrical apparatus, a casing for an electrical device undercut on an incline at one side and having end walls adapted for engagement by sections of conduit and in conjunction with the undercut incline of the casing forming a housing for an electrical terminal and an electrical terminal for the electrical device mounted in said hous ing.

9. In electrical apparatus, a, casing undercut at one side thereof, spaced apart flanges constructed for engagement by sections of conduit, and in conjunction with the undercut side of the casing forming a housing for an electric terminal, said housing being open :it one side, an electrical terminal mounted in said housing and a detachable cover closing the open side of said housing.
